The rear edges of the bed f are formed with lateral flangesf1l which will abut against the outer frame when the bed is insertedinto the same, `so that the bed is kept in operative position during theprinting operationV and an exact adjusting of the type form a is madepossible.

The frame also carries such .parts of'the machne which in thisspecification are not chine in such a manner that it can be adjustedrelatively to the type form bed, in that the spindle, on the sideA ofthe machine opposing the operators side, is connected to a pivot k2,which for instance may be located in a bore-in one of the standards Inthe constructional form of the invention shown in the drawings the upperend of the spindle is connected in such a manner to a head piece k1,that it can be rotated but not axially'displaced within-the same. `Thishead piece or Y sleeve 701 is directly connectedto the pivot 7a2.

The upper end of the `spindle 7c carries a bevel gear 7c3 the operationof which willfbe described in thefollowing specification." The spindlefurther carries a guide sleeve Z which is internally threaded and whichis pivotally connected to therupper end of the type form bed, in thatthe said bed is equipped with a bracket or Varm m and a laterallyprojecting pivot on the sleeve Z is taken up by a bearing-shaped part m1ofthis bracket. According to another constructional form of theinventionna pivot on the bracket m projects into a bore in the threadedsleeve Z. A threaded plate m2 keeps the pivot in position in the bearingm1, It will thus be understood that thev sleeve Z is pivotally connectedtothe type form bed and forms a threaded guide in which the spindle 7cis rotating during the upward and downward movementsfof theV type formbed f. An inspection of the drawings especially of Fig. l will make itclear thatwhen the spindle 7c is rotated the sleeve Z will ascend ordescend on the same in accordance with the directioniin which therspindle is rotated. Hereby the part of the spindle 7c between thesleeve Z andl the .head piece'lc1 willV be lengthened or shortened andthe inclination of the spindle will change according as the pivotof thesleeve Zis turned itsbearing m1. When the spindle 7c is rotated thesleeve Z and the type form bed will lthereupon be swung upward ordownward about the shaft g.

n the ccnstructional form of the invention shown in the accompanyingdrawings the threaded spindle Il: is operated by means of a gearmechanism. The lengthened pivot k2 carries a gear p1 which is rigidlyconnected to a bevel gear p2, which meshes with the bevel gear on thespindle c. The gear p1 meshes with a spur gear p3 which is fastened tothe shaft jv. VrThis shaft is supported by the machine standards ZJ andcarries at its free end a hand wheelo or a suitable lever.

When the hand wheel 0 and the shaft p are rotated the rotation is bymeans ofthe spur gear p1 and p3 transmitted tothe bevel gear p2 and tothe bevel gear 7c3 which again transmits the rotation to the spindle 7c,

whereby the sleeve vZ is moved upward or downward on the spindle c andthe type form bed is moved into orout of operative position. A

`The bed plate may forrvinstance be locked in operative position atbothv sidesby means of wedge bars 1' (Figs. 7, 8, 9), which can beshifted in vertical direction in the sides of the frame c `and which areformed with alternating projections r1 and gaps or slots r2. `In oneposition of the said wedge bar thebed 7 will be released `and in anotherposition it will be locked. The wedge bars r are arranged insuch amanner in parallel guide slots c1 in the frame members c onboth sides ofthe type form bar, that they can be displaced or shifted in. verticaldirection. The conical projections r1 project into the bed f,fwhichisformed with corresponding' conical guides and with open intermediatespaces through which the projections r1 are moved (Figs. l, 8, 9, 10).The wedge bars r1 are conlcally widened in upward direction andVcooperate in such a manner with correspondingly formed conicalprojections f2 on the type form bed, that the said bed is locked to itsframe when the wedge barsr are forced downward. The side of the wedgebars facing the type form bed comprises projections and slots, which arelocated in such a manner relatively to the corresponding projections f2in the-bed f, that the projections in the wedge bars will face theintermediate spaces between the projections f2 in' the bed f when thewedge barsare forced upward, i. e. out of locking position, so that thetype form bed will be released and can be swung downward.

When the type form bed has been brought into operative position by meansof the hand wheel 0 and the spindle 7c the wedge bars are lowered bymeans Aof a driving mechanism, whereby the conical projections of thebars will slide along the conical projections 'f2 (Fig. 8) and the typeform bed will be drawn4 into the frame until the flange f1 abutsagainst'f vpartly cover the wedge bars 1;

The type form a is fastenedV in a mannerv known per se by means of aclosing frame'j asa-Liese the member c. The raising and lowering of thewedge bars is effected by means of a hand wheel g1, which is fixed tothe hollow shaft Q, surrounding the shaft p (Fig. 2). On the hollowshaft g toothedsegmentsor wheels g2 are arranged, which cooperate withracklike upwardly directed parts ofthe-wedgev bars 7'. When the gears g2are rotated .by means of the hand wheel g1 and the shaft` g the wedgebars will be lowered or Yraised whereby the type form bed will belockedV or released. j

In order to prevent thewedge bars from dropping out oftheir guides c1,retaining plates r3 (Figs. 8, 1l) are provided 8 the upperand'loweredg'es Vof which are inclined in known manner. The loweredge ofY the closing frame rests 1n a Vhet or ledge 15 which is fixed to thebed f by meansy of screws or the like and the upper edge is held inposii tion by means of clasps u, which pressthe type form againstthelist z?. The clasps u are arranged on a common shaft u1, which islocated in the type form bed and carries'a wormgear u2, whichintermeshes with a worm a3.

This worm ua, is arranged perpendicularly to the axis of the shaft u1.The said worm ua can be rotated in the type bar bed'7 but canl not beaxially displaced. The adjustment ofv the worm is effected by means of akey or the like (Figs. 5 and 6). v

It will be evident that the'type form can Ybe easily and securelyfastened to the type form bed simply by rotating the worm a3 and theshaft u1 in such direction, that clasps 'u A are pressed against theframes. When the said parts are rotated in the opposite direction thetype form is again released. l

The type form bed is preferably also,

made adjustable relatively to the vprinting cylinders in such a mannerthat the type form can be moved nearer to the printing cylinders whenthe surface atthel type form is worn 01T. This can be elfected by knownmeans, for in stance by arranging the ends of the shaft in blocks whichare displaceably arranged in the members c.
